The Corvette Z06. It tops out at 198 mph, runs the quarter mile in 11.5 seconds at 127 mph, and hits 60 mph in a jaw-dropping 3.5 seconds (in first gear). All of that performance is the result of superior GM engineering and an engine we call the LS7, the most technologically-advanced small-block ever built. A natural continuation of the LS Family, the LS7 uses a 7.0L aluminum dry-sump block, CNC-ported cylinder heads, and titanium rods and valves to pump out 505 hp and 470 lb.-ft. of torque. Talk about efficient. The LS7 helps the Z06 get over 28 mpg while still being the fastest Corvette ever produced!
